VALVE.

No. 824,345 Specification of Application filed December 4,

To (all whom it Decoy concern:

Be it known that I, PHILIP C. MILLER, a citizen of the United States,residing at Chicago, in the county of (look and State of Illinois, haveinvented certain new and useful Improvements in Valves, of which thefollowing is a specification.

My invention is for use in connection with blowpipe systems where fansare used for handling solid matter, principally shavings and dust, andis placed in the discharge-pipe of the blowpipe system where thematerial is carried through a pipe and it is desired to defleet part ofthe material and to deposit it or discharge it at different points. Thisis generally done by means of a V placed to a junction where theseparation of the material is desired to be effected. In order to carrythe material along, it is under present conditions necessary to have thetwo branch pipes of the same diameter as the main feed-pipe. This is avery considerable expense, and especially where a long run is necessary,it sometimes being the case that the material has to be carried onethousand or fifteen hundred feet. Attempts have been mad e to insert avalve at the point of junction, so that you can close off one or theother of the branch pipes. This is subjected to two serious objections:first, that it does not assist in changing the diameter of the branchpipes, and, second, where it is swung from a central point to close thede sired pipe it is necessary in a valve of this kind that it should beloose in order to swing sufficiently free. The result is that portionsof the material are carried past, over, under, and around the said valveand deposited in the idle pipe. There being no air to carry it along, itbanks up and results in an effectual stoppage of this pipe, so that whenyou swing the valve back the pipe has to be cleaned out before it willbe of any use.

The only device with which I am familiar where it has been possible touse a smaller diameter of pipe for the branch pipes and still producethe results is where a valve is placed in connection with a series ofdeflectors to catch and turn the lighter material carried in the airtoward the bottom of the pipe and in this way deflect it into thedesired pipe. This is subject to the very serious objection that,especially on a long run, it is desirable to keep the shavings or othermaterial in the air, while its tendency is constantly to settle to thebottom of the pipe and eventually clog up the pipe.

My invention has for its obj ectto remedy these objectionable featuresand to produce a valve which will deflect any desired portion of thematerial in the desired direction and will at thesame time permit thepassage of such air through the opposite branch, which is closed to thepassage of material, so that there will be a sufficient area for thepassage of air through the two pipes, and as a consequence it will notbe necessary to have branch pipes of so great a diameter as the mainsupply pipe, so long as the sum of then combined areas equals the mainpipe, a very valuable feature commercially, as in a long run the expenseof the pipe is very consid erable.

My method of accomplishing the foregoing may be more readily understoodby having reference to the accompanying drawings, which are a part ofthis specification and are hereunto annexed, in which Figure 1 is asectional plan view showing my invention in connection with the feedpipes. Fig. 2 is a view taken on line X X in the direction indicated bythe arrows. Fig. 3 is a detail view of a modified form of constructionof the valve.

Similar figures refer to similar parts throughout the entiredescription.

In the drawings, 1 is a supply-pipe having branches 2 and 3. The valve 4is placed at the junction of the two pipes 2 and 3 and may be mountedupon a hinge 5 or in any other suitable manner. This valve swings, asindicated by the dotted lines and may be made to close either the pipe 2or 3 or may be swung to any desired point in the pipe 1, and thus willdeflect any desired percentage of the material in the direction wanted.

A series of openings 6 are arranged in the valve 4, the sum of the areasof these openings being equal to a desired area or more. Shields 7 areplaced over these openings, the result being that when the air carryingthe shavings or other material strikes the face of the valve when it isin the position shown in Fig. 1 the material is deflected by the guardsor shields 7, while the surplus air, following the direction indicatedby the arrows, passes through the openings and into the opposite pipe,thus keeping this pipe free from light Patented July 3, 1906.

material, which may be carried through the openings 7. It is obviousthat these openings may be in any desired shape, and the construction ofthe shields may be varied considerably without departing from the spiritof my invention, which is to provide vent the material passing throughsaid openfor the deflection of the material into the de-' sireddirection and permit the escape of the surplus uantity of air. A seriesof openings mig t be used, as shown in the drawings, Fig. l, or openingssimilar to those shown in the modified view may be used, or it may befound desirable in some cases to have one opening and the shieldextending over and around this. Any of these changes would be moremechanical alterations and would not deviate from the spirit of myinvention.

Having fully described my invention, what I regard as new, and desire tosecure by Letters Patent, is

1. In a device of the character described, the combination with a feed-pipe having branches, of a valve located at the junction of saidbranches, there being openingsof the desired area in said valve, guardsor shields arranged for said openings to deflect and preings, for thepurpose set forth.

2. In a device of the character described, the combination with afeed-pipe having branches, of means to deflect the material in thedesired direction, there being in said means for deflection means topermit the escape'of the surplus air, and means to prevent the passageof the material through said means for escape, for the purpose setforth.

3. In a device of the character described, the combination with a feedpipe having branches, of a valve to deflect the material in a desireddirection, there being means to permit the escape of the surplus airtherein, and

means to prevent the passage of the material through the said escape,for the purpose set forth substantially as described.
